2. Remove the air cleaner cover and air filter, and spray some fuel into the intake. You will have to hold open the little “door” inside there with something. If it starts briefy then dies you probably have a fuel problem. 3. You can jumper a hot wire to the fuel pump and listen to it whir to prove that it’s working.

Are there any problems with the Porsche 911 CIS?

Although the CIS has a reputation for reliability, it is also known for having a few characteristic problems. Warm and cold start problems are common, as well as backfiring and poor performance at startup. On the early 911s, the CIS didn’t even operate properly, until the car was warmed up.

When did Porsche 911 start using fuel injection?

In 1980, emissions requirements forced the introduction of an oxygen sensor into the system, which helped the engine to better run at the appropriate mixture level through the regulation of fuel pressure inside the fuel distributor. The two primary adjustments for the CIS are the idle speed and the mixture adjustment.

Why does my Porsche 911 have a cold start?

Cold start problems can often be attributed to the thermo-time switch or the warm-up regulator. For more information than you will probably every need on the CIS, take a look at the book, “Bosch Fuel Injection & Engine Management” by Charles O. Probst.

Why does my 911 SC not cold start?

The decel valve will, by design, allow “false air” to bypass the throttle when decelerating. Plug that stinker. Since you can’t start easily cold, I think you have a CSV issue. the CSV will overcome a host of cold start issues with a typhoon of gasoline laden vapor.

Where are the DME fuses on a Porsche 911?

All DME-related fuses are up front, but there are three fuses under the plastic cover at the left rear side of the engine compartment. 9. If you have one available, swap in a known working DME computer from a 911 friend. Be careful that you have the right production year and part number because there are differences in the pin mappings.

Why does my car not start when I crank the engine?

If the engine doesn’t crank, or makes an unusual noise when cranking, you may have a starting system problem. The car’s security system may have made an error that disabled the fuel or ignition system, or the chip in the key may have failed.

What to do if you don’t see a spark in your spark tester?

While watching the spark tester, have an assistant crank the engine. You should see a bright spark jumping the gap in the spark tester. If you don’t see a spark, repeat the test. This time, adjust the spark tester to 30KV. If still you don’t see a spark, repeat the test and set the tester to 10KV.

Why does my car not start after replacing the crankshaft position sensor?

I changed out the crankshaft position sensor on my car because it was losing power while driving and the code on an AutoZone scanner said crankshaft position sensor. After replaced with a new one, car had a rougher start, no loss of power but now, two days later, it won’t start at all.

Can a bad crankshaft sensor cause a cylinder to misfire?

Should you feel or hear a brief stutter in the engine, it may be a sign of misfiring cylinders from a bad crankshaft position sensor. A failing crankshaft position sensor cannot provide the right information about piston positioning in the engine, causing a cylinder to misfire.

What does it mean when your car cranks but won’t start?

Some car owners think that it means that the engine is running. To a technician, it just means that the starter is successfully engaging the flywheel and rotating the engine’s crankshaft. Some technicians will interchange this with the word “cranking.”

Check for a blown fuse that may be preventing a circuit from working properly, like the fuel injection or computer system. To operate efficiently, an internal combustion gasoline engine needs a good spark, the right amount of fuel, and good compression (a healthy mechanical condition).

Why is it bad to buy a Porsche?

A lot of people will have to pay more for a new engine than their car is worth. Because Porsche has not addressed this issue publicly and will not grant potential victims an extended warranty or a free mechanical fix of the problem, many otherwise good used cars are now tainted. It is certainly affecting resale value.

Why does my car not start when I try to start it?

Can a Porsche engine be rebuilt under warranty?

I recall reading about an owner in Britain who won a case against Porsche. The judge said that Porsche should be building engines that go 200,000 miles, not the crap that ends up in an IMS failure.

Why is my starter not working on my Porsche?

The most common reason is old wiring in the car. As the car ages, the wiring has a tendency to lose some of its electrical conductibility. This can be caused by the wires getting bent or crimped, or it can also be triggered by the constant heating and cooling of the wires.

Is there a problem with my Porsche 911 Carrera?

This “D-chunk” problem seems ironically to occur mostly in gently driven cars. 911 Carreras that are driven hard at the track or on the street do not tend to see this type of damage.

The root cause of this issue is open to discussion, however, wear in the piston rings and liners causes the piston to wobble.

Why is the Check Engine light back on on my Porsche 911?

The fault codes will suggest faulty O2 sensors. This results in many folks replacing the front O2 sensors in the hopes of solving the problem, only to discover that within a few hundred miles the check engine light is back on. The problem is actually caused by the MAF failing and by owners blindly believing the reported engine faults.

Sometimes, however, the ignition coils are the real culprit. They can cause serious problems if your vehicle has a one-per-plug system instead of a wasted spark system. The car can run if a few ignition coils are damaged or are faulty, but it won’t be able to start as easily or smoothly.

Where does the spark come from in an ignition coil?

The electric spark generated due to the high voltage is a quick electric discharge that occurs as a result of an ionized and electrically-conductive channel. The electric spark occurs in the spark plugs. The spark plugs are devices for delivering the electrical current from the ignition system to the combustion chamber of the engine.
